Consider the Structure
Solving the puzzle of the Rubik's Cube often requires a different way of thinking about the Cube itself. The traditional Rubik Cube is made up of 27 stickered sections, which can be referred to as squares, so individuals are often tempted to think of the Cube in terms of these squares. It's better to consider the Cube as six rotatable centers. Each face is defined by the color in its center, and also has edges and corners that move around it. Thinking about the Cube in terms of fixed color centers prevents you from trying illogical moves or making misguided assumptions about the color of each face.
Smoother Rotation
Some Cubes, especially recently purchased models, are stiff, with faces that are difficult to rotate. While having faces that are smoother and therefore easier to rotate won't tell you what to move when, it will allow you to solve the puzzle faster, which may be beneficial to some players. You can dissemble the Cube by popping the edges out. Once the Cube is in pieces, use Q-tips to coat the black spots of each component, as well as the Cube's core; this will lubricate the Cube and allow smoother rotation. Remember to reassemble the Cube in the solved position to avoid difficulties later, as suggested by the Massachusetts Institute of Technology website.
First Moves
A recommended first step when attempting to solve the Cube, according to the Eighty Eighty Nine website, is to choose one face of the puzzle, note the color in its center, and then attempt to move all squares of that color to that face. Look out for the face with the most usefully positioned squares to help you decide where to begin.
Correct Place
A useful marker while you're progressing through the Cube is that you can tell when you've got a piece in the right place, as the sticker color will be the same as that of the middle square within the face. This also means that while you may occasionally end up with squares in the wrong place, the center squares are always in the right position.
